While the ghost is blue, the Pac-Man is able to eat him, in which his eyes will pop out; he will regenerate after entering the Ghost Home in the center of the Maze.
The blue effect will wear off rather quickly, and will start to flash white when it is about to. In the original arcade Pac-Man and Ms. Pac-Man, the ghost will flash exactly nine times. This is different in some home console ports (like NES version of Pac-Man, where it flashes sixteen times).
Eating ghosts will award the player points. These are the scores earned by eating ghosts in succession:
- #1 in succession - 200 points.
- #2 in succession - 400 points.
- #3 in succession - 800 points.
- #4 in succession - 1600 points.
In some later Pac-Man titles where more ghosts can appear at once, these scores can also be earned:
- #5 in succession - 3200 points.
- #6+ in succession - 7650 points.
The rather random-seeming score of 7650 is actually a Japanese "Goroawase" wordplay on Namco (7=na, 6=mu, 5=ko, forming "Namuko").
